In cooperation with various government regulatory agencies, HP has announced an expansion of its June 2016 worldwide voluntary safety recall and replacement program for certain notebook batteries. Additional batteries are affected.

I've had this unit for over a year. I still like the design, but problems:

1. The photo black ink would intermittantly stop printing, and now has quit all together. Have cleaned cartrige (internally and externally) and although occasionally will get a little photo ink on a Quality Test, mostly nothing. All other colors continue to print just fine. Have concluded it is the printhead gone bad. How do I find the part number for this to replace? Have gotten a part number through numerous converstaions with HP but they have not been able to confirm this is the printhead for my C309. Help?

2. The photopaper feed has always been balky but now I have to extend one sheet out the back of the carriage in order for the printer to grab it; otherwise it says it is out of paper (and it is not).

3. I really don't care about the photo black ink (for photos and disks) but there doesn't seem to be any way to get it to just use the regular black ink.
